Introduction and Objectives With the ageing of the world population, the diseases proper to this phase of life take an undoubted epidemiological importance. The loss of cognitive abilities is an inexorable process of this evolution. It is essential to study ways to prevent such disability. Exercise has been suggested as an attenuating of cognitive deterioration reducing the risk of dementia. The objective of this paper is to review the existing evidence on the effect of exercise in preventing cognitive deterioration.
Methods Search meta-analysis, systematic reviews, clinical guideline standards and randomized controlled trials published between January 2004 and January 2014 using the terms MeSH: Exercise, Mild Cognitive Impairment, Dementia, Memory Disorders. The results were classified according to Strength Of Recommendation Taxonomy (SORT).
Results Physical activity is associated with a lower risk of developing mild cognitive impairment and dementia. There is evidence of improvement in cognitive scores after 6 to 12 months as compared to sedentary lifestyle. Furthermore, it was found that the aerobic exercise over 12 months correlates with larger volumes of the hippocampus and better spatial memory.
Discussion Currently there is enough evidence for doctors to recommend physical activity as a strategy for early intervention to prevent dementia. Several studies are now unfolding to better assess the impact of physical exercise and what is the best type of exercise in the prevention of dementia.
